Attempting to booth kernel-smp-2.4.18-5.74 on my dual-processor system fails early in the boot cycle, repeatedly printing this message to the console: APIC error on CPU0: 08(08) The system needs to be power-cycled to reboot it. Booting the same kernel with "noapic" works around the problem, and as a point of reference, 5.73 did not exhibit this problem.
